- Add .claude/, .mcp.json, CLAUDE.md, and AI-generated CSVs to .gitignore
- Add _notes/ vault (architecture, API, tasks, bugs, infra docs)
- Add .obsidian/ plugin/vault config (workspace state excluded)
- Sync CHANGELOG.md

+## Architecture Reminder
+- **Gamification + Reviews** → Node.js `app.eventifyplus.com/api/v1/` → `_nodeBase`
+- **Everything else** → Django `em.eventifyplus.com/api` → `baseUrl`
+- Key file: `lib/core/api/api_endpoints.dart`
+- State: Provider → register in `lib/main.dart` MultiProvider
+- Pattern: copy from `lib/features/events/services/events_service.dart`
+
